Making the transition from being a student to working 8 - 5 is really draining and difficult at first. I found it frustrating to be "trapped" for 9 hours day when I was used to having such a flexible schedule. It took me about a month or so to get over it, but what I did love was not having to study or do work on the weekends. For me, its hard to fit in long rides during the week unless I'm commuting, which you said you can't do. I agree its about priorities. When I was gearing up for my first metric I felt like I really needed to be putting more miles in, so I set a lot of other things aside (house projects, house cleaning, cooking) and rode as much as I wanted to. I once had a boss who said to me "You are only one person, and you can only do as much as one person can do." Its like the people who say they just don't have time to excercise, I say, I just don't have time to watch TV!
